Effects of various substrates on human hepatoblastoma and hepatoma cell culture.

The effects on human hepatoblastoma (HuH-6) and hepatoma (HuH-7) cell lines of collagen type I (CI), type IV (CIV), fibronectin (FN) and laminin (LAM) were investigated. CI and CIV promoted almost equally the attachment of both cell lines more strikingly than did FN or LAM. CI and CIV were also superior to FN or LAM in supporting the growth of HuH-6. These substrates, however, had no appreciable effect on the growth of HuH-7. The amount of alpha-fetoprotein (AFP) and albumin secreted in HuH-6 was found to be higher on FN- and LAM- coated substrates than on the other matrix material- coated ones. HuH-7 exhibited increased levels of AFP on LAM- coated substrates 4 days after plating. These results indicate that the ability of extracellular matrix materials to enhance attachment and/or growth is different from that to enhance AFP and albumin production in HuH-6 and probably in HuH-7.[1]
